The very first automatic I had, an Opel Rekord, I had a pukka Opel workshop manual for it. Bloody great thing - cost a fortune. In there one of the tests for the box was to measure its 'stall speed'. Handbrake on, footbrake hard down, select Drive and floor the accelerator. The stall speed was the revs the motor peaked at. Any of the real Vauxhall whizzes here know if this is still an accepted test and if so what the stall speed of an Astra box is? TIA Vin
